SPECIFICATION forming part of Letters Patent No. 613,371, dated November 1, 1898.

Application filed, March 29, 1898. Serial No. 675,577- (NO model.)

To all whom it may concern: 7 Be it known that we,EnMUNn HOFFMAN and ROBERT PORTES FRIST, citizens of the United States of America, residing in Bridgeton, in the county of Cumberland, in the State of New J ersey,-have invented a certain new and useful Improvement in Closures for Bottles or Similar Receptacles, of which the following is a true and exact description, reference be- 1o ing had to the accompanying drawings,which form a part thereof.

Our invention relates to cap-closures for bottles, jars, &c., having for its object to provide a sheet-metal cap at once simple, strong,

I 5 and especially Well adapted for use in closing bottles.

The nature of our improvements will be best understood as described in connection with the drawings, in which they are illus- 2o trated, and in which- Figure 1 is an elevation of a bottle-neck adapted for use with our closure and a cap embodying our invention. Fig. 2 is a perspective view of the bottle-neck. Fig. 3 is a central cross-section through the cap; Fig. 4,

a central cross-section through the cap on the line 2 2 of Fig. 3, and Fig. 5 is a central crosssection through the cap on the line 1 1 of Fig. 3.

0 A indicates the neck of the bottle, and A the top thereof, which is formed with vertical passages or slots 0, a, communicating on one side with inclined shoulders at, which in turn run into horizontal shoulders a 5 B indicates the metal cap, preferably made flat on top and with both sides extending at right angles to the plane of the top.

0 is a plate or layer of cork or other similar material, which we place in the cap before its 0 sides are corrugated, making it to nicely fit the upper part b of the cap. The walls of the cap below the portion 1) are then partly or wholly crimped or corrugated, as indicated at b, the crimps impinging into the lower edge of the cork layer and looking it securely and permanently in place in the cap, not only making it unnecessary to cement the cork in place, but holding it much more securely than it is possible to do by cementation.

Preferably instead of crimping the entire side walls of the cap we leave plain facets, as indicated at b*, and form inwardly-extending locking lugs or projections by forcing in a portion of the metal of these facets, as indicated at b b, and in order to give these lugs sufficient strength to resist strains to which they are subjected we form them with their upper contacting shoulders 19 extending inward abruptly, preferably at right angles to the face of the facets, While the lower sides b of the lugs slope gradually outward to the face of the facet, forming a brace Well adapted to resist the pressure coming on top of the lugs. Preferably, also, we form the top face of the locking-lugs parallel to the top/ of the cap.

In operation the lugs of the cap are brought to register with the passages a in the top of the bottle and pushed down through these passages and then turned so that the corner of the lug will ride down on the inclined shoulder a the depth of which is sufficient to insure the necessary compression of the cork layer 0. A further turning of the cap brings the lug beneath the horizontal shoul 7 5 der a where practically its entire length rests in contact with the shoulder, thus availing of the entire strength of the lug to hold the cap. in place. To open the bottle, it is only necessary to turn the cap in the reverse direction.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A sheet-metal cap with cylindrical sides for closing bottles and similar receptacles having athin layer of cork or similar elastic material situated at its top and secured in place by a series of longitudinal crimps formed in the sides of the cap and pressed into the lower edge of the cork layer after said cork layer is inserted.

2. A sheet-metal cap for closingbottles and similar receptacles having its sides formed into plain facets, as 19 indented to form inwardlyextending lugs and longitudinally crimped between said facets to afford a good holding-surface.

similar receptacles having a layer of cork or 15 similar material at its top, inwardly-projecting lugs as b b formed in its sides above their bottom edges and running parallel with its top in combination with a bottle-neck as A formed with vertical passages a and inclined shoulders at terminating in shoulders a parallel with the top of the bottle.
